Easier and smarter to 'fix' a possible/probable bad situation before it happens than after...and considering the tone of the insurers caution & warning ~ we may already be at the front end of the 'after'.

I'm not aware of anyone opposed to a standardized curriculum.

All the objections I am aware of relate to creating a USPA rating system parallel to AFF (with WS-I, WS-I/E, WS course directors, evaluators, etc) with all the bureaucracy that entails.

It doesn't take a USPA rating to tell someone to keep their wings closed on exiting the plane. Even you and I could do that.
